3D computer graphics software used for visual effects, art, interactive video games, and animated films. 3D models can be modeled with Blender, and animated using various keyframed modifiers such as inverse kinematics and vertex weighting.

Blender uses very little diskspace and contains many of the same features found in high-end 3D computer graphics software. The user interface is considered to have a steep learning curve, but work has been done to redesign the interface to create a comparable experience to commercial software. Blender is popular with scientific users and is a dominant open source project.
